The Difference

To construct 3D ordered hierarchical materials, Si, Al and Ti colloids precursors were controlled prepared via dual template method in which the colloidal crystals and P123 acted as hard-template and soft-template, respectively. The results showed that ordered hierarchical SiO2, Al2O3 and TiO2 were successfully prepared. The difference of the structure of samples suggested that hydrolysis rate of the precursors play an important role on pore structure of the samples.

Diallyldimethylammonium Chloride

In this article, we proposed a new platinum (Pt) nanoparticles ensemble-on-graphene (G), a new electrode material, which was rapidly prepared by microwave-assisted reduction of PtCl62- on the poly (diallyldimethylammonium chloride)-modified G. The Pt/G hybrid can be directly used as electrode materials. The microstructure and morphology of the prepared film samples are characterized by TEM, and the result showed that Pt nanoparticles with averaged diameter of 2~5 nm appear as dark dots on the surface of graphene. At the same time, the electrocatalytic activities of the Pt/G hybrid modified electrodes towards methanol oxidation is evaluated through cyclic voltammetry. The as-synthesized Pt/G hybrid exhibits high catalytic activity and good stability for the oxidation of methanol, which may be attributed to its excellent electrical conductivity and the high specific surface area of the graphene catalyst support.
